History of Astronomy for the Year 1805. 251 
surement of ground, as well as to the preparation of the 
eanvas for charts and maps; by L. Puissant, professor of 
mathematics in the Imperial Military School: 400 pages in 
Ato. price 18 francs; Paris, chez Courcier. 
We find in this book plenty of astronomical problems 
necessary for drawing of charis, tables for the spheroids, and, 
in particular, a complete description of the repeating circle, 
with excellent plates. 
Manuel de Trigonometrie Pratique, by M. V’abbé Dela- 
grive, of the Royal Society of London, and geographer in 
the city of Paris ; revised, and augmented with tables of lo- 
garithms for the use of engineers, particularly land-survey- 
ors: by Reynaud, professor of Jand-surveying in the Poly- 
mathic School; 1 vol. 8vo. 352 pages, with 6 plates; Paris, 
chez ae price 7 francs. 
Trigonometrie Analytique, preceded by the Theory of the 
Logarithms, by Reynaud ; Courcier, 1805, in 18mo. There 
are here added tables of logarithms made upon my small 
stereotype tables, but which are probably far from being so 
exact as mine. 
M. Benzenberg has published a book in German, where 
we find his experiments upon the fall of bodies, Versuche 
uber das Gesetzx des Falls: 1 spoke of this last year. He 
found a deviation of 12 millimetres and a half for 86 me- 
tres; but the extremes differ by six millimetres, on account 
of the great difficulty of the observations. 
M. Benzenberg has also sent us some curious observations 
upon the shooting stars; he observed 500 of them in one 
night; he shows how they may be made useful in deter- 
mining longitudes. Having so concerted with M. Brandes, 
who was 25 leagues distant from him, he found the distance 
of these meteors to be from 5 to 60 leagues.’ 
M. Adrian Duquesnoy has published the first two volumes 
of Asiatic Researches, or Memoirs of the Society established 
in 1784 at Calcutta in Bengal; translated by A. Labaume, 
with notes of Messrs. Langlés, Delambre, Cuvier, Lamarck, 
and Olivier. There are seven volumes of this collection pub- 
lished, but they contain scarcely any astronomical memoirs 
Peerving of the trouble taken by M. Delambre to render 
them
